Footman James are just a specialist insurance broker and the underwriter that they used for most of their classic policies (Equity Red Star) no longer insures under 21's, so they have had to find an alternative provider that does. The new provider seems to have higher premiums, which is the reason for the increase.
Reducing your mileage limit may reduce your premium to some extent, but in my experience it doesn't make a huge amount of difference unless you are reducing the mileage drastically. Also some insurers have a set minimum mileage limit, so you may find that reducing it from say 5,000 miles to 3,000 miles per year makes no difference, if 5000 miles is the minimum amount. This will differ from insurer to insurer though, so you need to check with Footman to see if it will make a difference in your case.
If your car is taxed, then legally it now has to be insured as well. So if you choose to take your car off the road for a few weeks and not insure it, then you will have to declare it as SORN. Be aware though that you will have to then surrender your TAX disc and send it off to DVLA for a refund. I believe that the DVLA only refund you to the value of nearest complete month of tax remaining, so depending on when you surrender your tax disc, you could lose out on the cost of up to 29 days or so of road tax. The other issue is that if you take your car off the road for a few weeks and don't insure it could still be stolen from wherever you keep it . Without any insurance you would get nothing back if this were to happen.
You should be able to request a letter of "claim free driving" from Footman as soon as you leave them, or your policy with them lapses etc. Assuming that these letters work in the same way as conventional "proof of no claims bonus" does, then insurers tend to accept such proof so long as it is issued within the previous two years. So you should be able to use one of Footmans "claim free driving letters" against another policy with another insurer for the next two years or so, (so long as they actually accept Footmans "claim free driving letters" as proof of no claims, that is!)
